METHOD OF ATTACI-IING RUBRER AND LEATHER HEELS TO SHOES.

Application filed December 22, 1921.

T 0 all whom z': lmay concern:

Be it known that I, GILBERT F. QUINN, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented a new and useful Method of Attaching Rubber and Leather Heels to Shoes7 of which the following is a specification.

The object of my invention is to provide a novel method for temporarily combining or assembling a rubber top lift and a leather or composition base in their proper position relative to each other so that the entire heel base and rubber top lift can be at tached to the shoe in the shoe factory with one nailing operation on the heeling machine.

In the accompanying drawings illustrating my invention, Figure l is a perspective view of the heel applied to a shoe; Fig. 2 is a vertical section through the heel on line 2--2 of Fig. l; and Fig. 3 is a similar section taken after the nails for securing the heel to the sole have been driven into place.

Like numerals designate like parts in each of the several views.

In carrying out my method of assembling the leather or fibre heel base l' with the rubber top lift 2 I temporarily fasten the two parts together with suitable metal or wooden pegs or tacks 3 from the inner surface of the base through into a portion of the rubber top lift as at 4t, the top lift 2 being thereby held in its properly'centered position until it is inserted into the heeling ma chine when the regular or usual rubber heel nails 5 are driven into their proper nail holes 6 in the rubber top lift and through the washers 7, as shown in Fig. 3, and going through the entire mass, and thereafter being clinched, as at S on the inside of the shoe, as shown in Fig. 3, where the clinched ends 8 engage the sole 9. Y

The shoe manufacturer in the past has been attaching the base with one operation and the rubber top-lift with another. In some shops they have been coating the base and then the top-lift with cement and then employing girls to assemble them together which is expensive. Some rubber heel mak- Serial No. 524,247.

ers have been vulcanizing the two parts together for the shoe factory which is also much more expensive and unsatisfactory owing to the high percentage of imperfect heels which this method produces in the rubber heel factory. My new method. produces a perfect result of base and toplift assembly in every instance with practically no additional expense of labor or equipmentto the heel maker and therefore l be lieve it to be a new and novel method. Also, as I drive the temporary nails 3 from the inner surface of the base through into a por tion of the rubber toplift and not completely through said rubber top-lift I do not deface or mark the outer surface of the rul ber top-lift in any way whatsoever, thus leaving the regular nail holes of the rubber top-lift free to receive the regular rubber heel nails which permanently fasten the entire mass to the shoe.

My heel is the only one known to the trade that can be attached. by the heeling machine without the use of cement to make the edge oit the rubber heel fit tight to the leather base. Jall othertypes of rubber top-lifts now in use by the shoe factories must be cemented separately before they can be applied to the base.

Heretofore all rubber top-lifts known as being of the concavo-convex type have been sold to the cobbler trade only for hand attaching as the heeling machine in the shoe factory cannot attach a. rubber heel unless it lies flat; My new method of temporarily nailing the rubber heel to the leather base7 flattens this concavo-conver; type of heel on the base thus opening` a new and much larger trade to the maker of' this style of heel, while still retaining the new improvement of avoiding the use of' cement to effect tight joint between the rubber top-lift and the leather base.
